XDS-I.b Abstract / Scope
Sharing of Imaging Information across affiliated
health enterprises
Imaging Information includes
 extensive sets of DICOM instances including images,
evidence documents and presentation states
 diagnostic reports provided in a "for display" form
 selection of diagnostically significant images
associated with the report content
www.ihe.net
XDS-I.b Value proposition
Imaging component of the Electronic Health Record:
Shared imaging Record, in a community, region, etc.
Effective means to contribute and access imaging
documents across health enterprises.
 Without XDS-I.b, access to the radiology report across health
enterprises is difficult
Scalable sharing of imaging documents between
radiology departments, private physicians, clinics, long
term care, acute care with different clinical IT systems.
Easy access: Care providers are offered means to query
and retrieve imaging documents (images and reports) of
interest
 using the same mechanisms used to query other documents

What’s New in XDS-I.b
New Provide and Register Imaging Document Set
Transaction
 Updated to use MTOM/XOP Transport mechanisms
 Fully compatible with existing XDS.b Repositories and Registries
 More heavily leverages XDS-SD for CDA-wrapped text reports
New Retrieve Imaging Document Set Transaction
 Web services based retrieval of DICOM images
 Based on XDS Retrieve Document Set Transaction
Key Actor Requirements
 Imaging Document Source is required to support all retrieval
types; Imaging Document Consumer can choose
“Old” version of XDS-I is simultaneously deprecated
 No more “SOAP with attachments” based Provide transaction
www.ihe.net
XDS-I.b Dependencies
XDS-I.b depends on IT Infrastructure Cross-Enterprise
Document Sharing (XDS)
Profiled XDS metadata with radiology specifics
 Acquisition Modality (e.g. CT, MR)
 Anatomic Region (e.g. Arm, Elbow, Hand)
 Requested procedure (e.g. MRI Knee with contrast)
Reuses CDA-wrapper defined by XDS-SD for plain text
reports.
XDS-I.b specific Actors
 Imaging Document Source
 Imaging Document Consumer (must be grouped with XDS
Document Consumer)
XDS Actors reused
 Document Consumer, Document Registry, Document Repository
www.ihe.net
Implementation Considerations
XDS-I.b security considerations
 XDS-I.b actors must be grouped with ATNA Secure
Node or Secure Application Actor
 Document retrievals must be capable of being done
across a protected (encrypted) channel.
Implementation Resources (XML schemas and
WSDL)
 Will soon be available via link at http://wiki.ihe.net/
